+	* xreadlink.c (MAXSIZE): New macro.
+	(xreadlink): Use it instead of SSIZE_MAX.  Ensure initial buffer
+	size does not exceed MAXSIZE.  Avoid cast.
+	As suggested by Mark D. Baushke in
+	<http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00009.html>,
+	if readlink fails with buffer size just under MAXSIZE, try again
+	with MAXSIZE.
